I reckon the solution is this...
Do some deal with a t.v production company,build a house somewhere,a field in Oxfordshire maybe,with various rooms,a diary room (or dairy room if there are still cows in the field) and so on,and put loads of hidden cameras in it.Call the programme Fairport Convention:Air Your Contention or Full House.
Lock each line up of the band in it as they occured originally,so start with Jude,Simon,Richard,Ashley and Ian,and each day,someone has to go into the diary room and is given a subject about the bands history to discuss in order to win a days food.
The members then reminisce,discuss,argue about that subject,until a consensus is achieved and the task is completed.The next line up is then assembled and the process is repeated until the truth is presented for publication.
I can see it now:
Geordie bloke (played by Bob Fox):Day twelve - Simon,Richard,D.M,and Swarb are in the garden,when Peggy has something to say:
Peggy:Well I remember it
perfectly, I poured me cider,and I opened the fridge to get me kippers,and they were
gone.
I didn't eat 'em so who did,eh?
Richard:Well don't look at me,I was in the garden practicing my archery,trying to get that bloody peacock out of the tree.
DM:I was practicing on my new triangle.What a bargain
that was,did I tell you about the kid? He was...
Peggy:Yes,Dave,about a million times....that's not relevant anyway....I want to know who ate me kippers!
Simon:And what about my shampoo? I was running a bath and I couldn't find it anywhere,so I had to go into Little Hadham to buy some more,and when I got back,the water was cold.Again.
Swarb:It couldn't have been me....I was moving me bed.
Peggy:Peacocks!Triangles!Shampoo!Beds!WHATABOUTMEBLOODYKIPPERS?
Richard (mutters):And you wonder why I went solo.......
Simon:Hang on....If it wasn't Me,Richard,Dave,Dave or Dave.....it must have been....
Simon,Richard,Peggy,Swarb,D.M:THE MIGHTY GLYDD!!!!!!!!!!!
A ratings winner,I reckon!
